@arr/map
A tiny, faster alternative to native
Array.prototype.map
:warning: Unlike native, @arr/map
does not support the optional thisArg
parameter!
:warning: Unlike native, @arr/map
does not respect Array holes -- you probably never needed this... :thinking:
Install
$ npm install --save @arr/map
Usage
import map from '@arr/map';
const nums = [1, 5, 10, 15];
const doubles = map(nums, x => x * 2);
//=> doubles is: [2, 10, 20, 30]
//=> numbers is: [1, 5, 10, 15]
